This species has usually passed as C. quadricolor (Vieill.), but, as Count Berlepsch 

 has shown ^\ it cannot be that bird, the description of which, founded upon a specimen 

 said to have come from Trinidad ', better suits Cyanomyia franciw of Colombia than the 

 present species. 



Count Berlepsch proposed to call this bird Uranomitra ellioti ", but Lichtenstein's 

 title, Trochilus verticalis, a synonym, according to Cabanis and Heine, of C. quadricolor, 

 may be used for it, based as it is upon Deppe's specimens collected in Mexico. 



The range of C. verticalis is chiefly confined to the sierras of North-western Mexico, 

 from Mazatlan southwards through the States of Jalisco and Aguas Calientes *. The 

 most southern place whence we have received specimens is Zapotlan, which is on the 

 south side of the Eio Lerma and Lake Chapala. Floresi's specimens, of which Gould 

 had a number in his collection, were probably all obtained at or near Bolafios. 



M. Boucard tells us that he and M. Salle found this species at a great elevation on 

 the peak of Orizaba during an excursion to that mountain ^. No specimens were 

 obtained on Popocatepetl by Elwes and Godman in 1888, nor did Mr. Richardson find 

 it on the upper parts of Ixtaccihuatl ; but Herrera and other writers on Mexican birds 

 say that it occurs in the Valley of Mexico, and M. Boucard says he found it breeding 

 at Choapam in the month of March *.

 this species from Sonora. It has not yet, so far as we know, been described.
